Actin Structure




Analyzing the Importance of Residue 204

A204 is a key residue in the structure of actin. Highlight A204 in G-actin and in F-actin

The filamentous structure of F-actin is made of individual G-actin subunits bound to ADP. Click on the Jmol menu in the lower right-hand corner of the F-actin window. Select "Main Menu" then "All 5 models". Select the "1.3: 3" option. Return to the Jmol menu. Select "Main Menu" then "Zoom" then "200%". Now you can see the G-actin subunit that looks identical to the one in the window to the left.
